  ABSTRACT: The biointeractions between a series of new organometallic carborane derivatives and model protein bovine serum albumin (BSA) were investigated by means of fluorescence and synchronous spectroscopy. The observations demonstrate that the ferrocene-carborane conjugates (FcSB1, FcSB2 and FcSBCO) and the ruthenium(II)-arene carborane complexes (RuBFc and RuBCOOH) can form a steady complex with BSA and statically quench its fluorescence. The ferrocene-carborane conjugates could remarkably affect the tertiary structure of BSA and induce the microenvironment changes of Trp and Tyr residues from hydrophilic to hydrophobic environment. But the effect of the ruthenium(II)-arene carborane complexes on the tertiary structure of BSA is much less. This study would give meaningful insights into the evaluation of the promising biomedical applications of the new carborane derivatives and benefit the development of potential multifunctional metallodrugs.

  ABSTRACT: Two new ruthenium(II) arene complexes, 2a (C(24)H(34)B(10)FeRuS(2)) and 2b (C(15)H(26)B(10)O(2)RuS(2)), bearing a carborane unit and other different functional groups were synthesized, and their cytostatic effects on cancerous cells were evaluated. Our observations illustrate that a structural change from a ferrocene unit to a carboxyl group could lead to high selectivity toward cancer cells and facilitate the efficient inhibition of the proliferation of target cells, indicating that the tuning of the overall properties of the ruthenium(II) arene complex by appropriate ligand tagging is critical to creating a selective antineoplastic agent.

  ABSTRACT: The addition reactions of the 16e half-sandwich complexes (p-cymene)M(S2C2B10H10) (, M=Ru; , M=Os) and Cp*Ir(E2C2B10H10) (, E=S; , E=Se) with ethynylferrocene lead selectively to the 18e complexes (p-cymene)Ru(S2C2B10H9)(H2CCFc) (Fc=ferrocenyl) (), (p-cymene)Os(S2C2B10H9)(H2CCFc) (), Cp*Ir(S2C2B10H9)(H2CCFc) () and Cp*Ir(Se2C2B10H9)(H2CCFc) (), in which the alkyne is regio- and stereoselectively inserted into one of the M-E bonds that may further lead to metal-induced B-H activation, hydrogen atom transfer from the carborane via the metal center to the inserted alkyne, and the generation of a M-B bond. In all complexes the S-eta2-(Fc)C-C and C-B(M) moieties occupy a cisoid position. The four new complexes are characterized by IR, MS, NMR spectroscopy and microanalysis, and the X-ray structural analysis of is performed. was observed to promote the uptake of anticancer drug daunorubicin in drug-resistant leukemia K562 cells.
